Photocatalytic Inactivation as a Method of Elimination of E. coli from Drinking Water

The presence of microorganisms, specifically the Escherichia coli, in drinking water is global concern. This mainly due to health implications these pathogens. Several conventional methods have been developed for their removal; however, this pathogen still found most water. In continuous quest a more effective removal approach, photocatalysis has considered as an alternative method elimination pathogens including E. coli from Photocatalysis many advantages compared methods. It offers advantage non-toxicity and utilizes energy sunlight, thereby making it completely green route. Since photocatalysts could only be active ultraviolet region solar spectrum, which less than 5% entire challenge associated with design system harvest complete utilization photocatalytic process. review, different inactivation mechanism involved process were reviewed. Various strategies that adopted order modulate band gap explored. addition, estimating detecting presented. Furthermore, reactor designs examined. Finally, kinetics was discussed.
